Fix hare new line insert indentation after comments

[stacyharper]

At the moment, inserting a new line while being in a comment result in a //<indentation> instead of <indentation>//.

To fix this, we just re-ordre both InsertChar hooks.

I remember that the hook order was relevant for some other reason, and that we are not consistent about that.
IIRC for the more complex file types it's convenient to use a certain hook order, for others it doesn't matter.

Probably the hare module would be better of staying closer to established filetypes. For example, go.kak does not have this problem despite using the same hook order

hare-insert-on-new-line includes a snippet that does

# remove trailing whitespace on the above line

Other filetype highlighter seem to have the same feature but implemented in a different way.
That function could probably just be (untested)

define-command -hidden hare-insert-on-new-line %{ evaluate-commands -draft -itersel %{
    # copy // comments prefix and following white spaces
    try %{ execute-keys -draft <semicolon><c-s>kx s ^\h*\K/{2,}\h* <ret> y<c-o>P<esc> }
} }

I pushed an alternative fix instead of this re-order one. Basically, replacing `P` with `p` make the comment symbol + indentation to be paster AFTER the initial new line indentation.

the initial version has been merged with 5314e23. Fair enough
